Use the product message routing capabilities to control server traffic flow.
You can route many of the BBO prefixed error messages to specific datasets instead of having them go to SYSLOG, which can create a lot of traffic. This is implemented with the use of two environment variables, ras_default_msg_dd and ras_hardcopy_msg_dd, and the specification of the appropriate DD statement in your JCL start procedure.
To set this environment variable, on the administrative console, click
, select a scope, and click New.If you are running on z/OS Version 1.12 or earlier, and using JES2, the SEGMENT= parameter can be added to the SYSPRINT and SYSOUT DD cards if you want to segment output using the periodic writing of form-feed characters to the output streams. Form-feed characters are written to the output streams based on the values of the ras_stderr_ff_interval, ras_stdout_ff_interval, ras_stderr_ff_line_interval, and ras_stdout_ff_line_interval environment variables. These variables are described in more detail in the topic Application server custom properties for z/OS The SEGMENT= parameter is not supported on JES3.
